Abstract: A vent assembly has a housing defining a cavity, a first end, a second end, a vent opening, a valve opening, and a coupling structure towards the second end. The housing defines a valve opening and a vent opening. A vent is coupled to the housing across the vent opening, and a one-way relief valve is sealably disposed on the housing across a valve opening.

Abstract: A vent assembly has a housing defining a cavity, a first end, a second end, and a coupling structure towards the second end. A mounting surface is positioned between the first end and the second end within the cavity and defines a valve opening and a vent opening. A vent is coupled to the mounting surface across the vent opening, and an umbrella valve is sealably disposed on the mounting surface across a valve opening.

Abstract: The technology encompassed by the current disclosure generally relates to membrane composites that can be used in acoustic venting assemblies. In one embodiment of the technology disclosed herein, a venting media composite has a microporous membrane layer and a coating on the microporous membrane layer to form a composite. The basis weight of the composite is at least about 0.5% higher than a basis weight of the microporous membrane layer without the coating. In some embodiments the composite has a decreased insertion loss than its membrane-only counterpart.
